Audio - Metallic Feedback Vibrations???

Camtasia 9. Play video from website... when I try and record it and then play it in Camtasia, the audio isn't very good. Volume level is fine but it's like I get a metallic vibration going on. I turned off the mic thinking that would help but it hasn't.

I can try on another device but didn't know if this was something common that this newbie is overlooking.
